Go via POSIXct and you want to set a TZ there -- here you see my  Chicago  default   R gt  val  lt - 1352068320 R gt  as POSIXct val  origin  1970-01-01    1   2012-11-04 22 32 00 CST  R gt  as Date as POSIXct val  origin  1970-01-01     1   2012-11-05   R gt     Edit  A few years later  we can now use the anytime package   R gt  library anytime  R gt  anytime 1352068320   1   2012-11-04 16 32 00 CST  R gt  anydate 1352068320   1   2012-11-04  R gt     Note how all this works without any format or origin arguments
